Dear friend!
As you mentioned in your previous post, there are different methods for configuring the Option82 tag in different scenarios.
Option82 involves many devices. The tag you carry must be identified by the BRAS on the network side. If the BRAS fails to identify the tag, the BRAS does not enable the corresponding device to go online. The BRAS identifies the tag, not the customer who wants to configure the tag. The configurations on both ends must be the same.
Therefore, you need to provide more details before we can provide you with a solution.
To effectively communicate with each other in real-time and quickly solve problems for you, contact Huawei local TAC to create a trouble ticket.
